A ‘Trademark opposition’ means an objection filed by third parties, against the registration of a trademark within 4 months of the advertisement of the trademark to be opposed. In the process of registering your trademark, there are two instances where a provision of refusal can be raised against the registration of your mark- The first instance is known as an Objection the second instance is known as an Opposition. After the examiner reviews your trademark and finds that it qualifies for registration, your trademark will be published in the Trademarks Journal. The purpose behind publishing a Trademark in the Journal is to enable any third party to view the trademark and file a trademark opposition against it. Once advertised, the trademark is open for opposition purposes for a compulsory period of four (4) months. In case no opposition is filed within this stipulated time period, the mark proceeds to registration.
